No modification of the actual class is done at all - the cache

happy.
So since a reference is stored, it means that the destructor of the
enclosing object is only called once not only the variable holding
the object, but also all lambda functions that were created inside
of the class have been free'ed?
I'm not up to date on the operation of the current patches to
implement closures, but typically this is how it'd work, retaining
references to what's needed as long as the closures exist.
